MECHANICAL MOVEMENTL Application filed May l0,

sides in the construction and arr: ngement oi parts hereinafter described and claimed, and

t illustrated in the accompanying drawings in which Figure l is an elevational view partly in section o't a wave motor unit, this view being broken away, and

Figure 2 is an enlarged detailed view looking 'troni the opposite side of that shown in Figure l. p

In carrying out my invention I provide an octagonal structure, comprising sides 31.

Secured to the sides 31 ot the mentioned octagonal structure, are guides 33 extending downwardly into the water and connected at their lower ends by a structure 35. Within the guides is disposed a float 36 tapered at its upper and lower ends and having a cylindri cal body portion. Secured to the cylindrical 'portieri ot the iioat 3G at spaced intervals are iiunnbers 33 in which are mounted shafts 39, en -h (arri-ying a roller 40LL lit-ting into a groove ot one oit the guides 33. i

irleans are thus provided whereby the iloat may readily be raised by the waves and fall by gravity and whereby the float may be guided. T he tloat 36 at its top is connected to a double rack 40 by means of a ball and socket 'joint 4l. It will be seen that the double rack 4() is provided with teeth 4Q on one side and with teeth 43 on its other side, and has a cen Aral slot 44 extending longitudinally thereot.

The teeth 42 oi' the rack 40`are adapted to engage a rotatable gear wheel 45 mounted ou a. sleeve 45n which is carried on `a shaft 46, sulviported by a trarne 47 while the teeth 43 are adapted to engage a gear wheel 48 mounted on a sleeve 43LL carried by a shaft 49 supported in the frame 47. The gear 45 is secured to an annular disk or wheel 50 which carries pivotally mounted dogs or pawls 51 which extend beyond the periphery of the 1926.11 Serial No. 108,133.

ratchets formed respectively in the fgear wheels 53 and`57. i

The gear wheels 5G and 57 are mounted on the shafts 4G and 49 respectively. wheels 56 and `57 of each wave motor unit are adapted to engage a gear59fwhicli is mounted on the power shai't15.

It will be seen from the foregoing that as the float is raised by the tide and waves, the rack l0 is also raised, and while being raised The gear i the gear 43,:ind therefore the disk 5,3 is turned in a clockwise direction when looking at Fig. 2 so that the dogs 54 Will engage the internal ratchet of the gear wheel 57, causing the latter to rotate and turn the gear 59 which is iixedly mounted on the power shaft l5. Each dog is pressed outwardly by a spring (not shown) to keep it engaged with the ratchet.

It will further be seenthat on the upward stroke of the rack 40 the gear Wheel 45 will be turned counter-clockwise and that the disk 50 will also be Vturned counter-clockwise. However, thepawls 5l, in moving counterclockwise, will not lock with the internal ratchet oitl the gear wheel 56. On the downward stroke of the rack 40, however, the teeth 42 oi the rack will engage the gear 45, turning` the latter clockwise, which causes the dogs 5l to engage with the internal ratchet of the gear wheel 5G, andto turn the latter which then transmits powerto the gear 59;

In the apparatus of my invention .l pro-` i I vide two pairs ot spaced rollers abutting against the `opposing sides oit the rack 40 to guide the latter, these rollers being indicated `by the numeral 60, and clearly shown in Figures l and 2. These rollers are mounted on shafts 6l and are suitably supported. y Furthermore, to provide lateral guidingmeans for the rack I employ two pairs of rollers 62, which pass through the slot 44 of the rack and are mounted on shafts carried by the frame 47.

According to my invention Iprovide means for rendering the device inoperative, and such means are hereinafter.. shown as comprising a brake wheel 65 and another brake wheel 66. The brake wheel 65 has secured to it a gear wheel 67 which engages the teeth 43 of the rack while the Wheel 66A has secured to it :i geerivheel 69 which engages the teeth 42 of the rack. A brake band 70 is provided in order to brake the Wheel 65. The brake band being secured at its lower end to un operatinglever 71 pivoted at 72. The other end of the brake bend 70 is secured to the freine i7 et :1. point 73. A brake bund 75 is provided for the Wheel 66, the lower end of this brake bend being' secure-.d to the frnnle 47 While its Upper end is Secured to the lever 71 above `the pivotal point of the lever, :is indiated by the numeral 7 (i.

Thelever 7l han associated with it` n. loci:- ingI menne 78 which et its lower end nmyengage toothl formed in an arcuate member 79, Shown in Figure l.

It will be readily seen that al.- movement of the lever 71 towards the leftwill tighten the bands 70 and 75 on `the wheels 65 and (i6, thereby preventing theste Wheels 'from .rotei'- ing und looking the gear wheels; 67 zmdGQ With the rack 40.

It `will beV `readily appreciated that the shaft 15 may be rotated by a number of units identical to the one described.

Thile I have described one embodiment of my invention, modifications: thereof may be readily devieed Without departing' from the spirit oi' my invention, end it is to be Underetood that enoh inodilientions come Within the scope of the appended claim.
